Soon, Tenzhi 1 adjusted the gravity parameters after shaking violently several times, and then entered a calm state.
In the video screen, there is no longer large jitter, and the screen begins to show a vague arc angle of the earth.
"The picture has become much clearer." Sun Zhongyong said.
Chen Mengchuan nodded. "In the stratosphere of the earth's atmosphere, there is relatively little water vapor, suspended solid particles, impurities, etc., the weather is relatively clear, the light is also very good, and the visibility is very high."
"The current speed has reached 200 kilometers per hour. If we continue flying for a few minutes, we will start to enter the middle layer. By then, the speed should start to increase significantly, and the temperature will drop again." Toni said calmly.
"This atmosphere is a bit interesting. The temperature is sometimes high and sometimes low. I didn't learn much about geography before, but now I feel a little regretful." Sun Zhongyong said with a smile.
Several people also laughed, and then Chen Mengchuan gave him a brief introduction to science.
"The mesosphere is a special layer in the atmosphere, with the stratosphere below and the thermosphere above. The temperature in the mesosphere decreases as altitude rises, so there is quite strong vertical movement in the atmosphere. Since it is between the highest altitude that an airplane can fly and the lowest altitude that a spacecraft can fly, it can only be entered using suborbital rockets. Because of this, the mesosphere is the layer of atmosphere least understood by humans."
"Furthermore, the mesosphere also fluctuates in temperature with seasonal changes, but this fluctuation is the opposite, which means that the temperature in summer is much lower than in winter. In winter, atmospheric gravity waves break and transport westward momentum in this layer, which is like exerting a westward drag force."
"In order to balance this drag force, the atmosphere must move in the polar meridional direction to obtain the eastward Coriolis force."
"This meridional movement from the summer pole to the winter pole causes the atmosphere in the summer pole to rise, causing adiabatic expansion and cooling; the atmosphere in the winter pole to sink, and causing adiabatic compression and heating."
"The influence of this circulation on temperature exceeds the radiative heating of the sun. Therefore, the temperature at the mesosphere is the coldest in the summer poles where there is direct sunlight, and the hottest in the winter poles where there is no sunlight."
"So, the mesosphere temperature in summer will be as low as below 100°C, which will be much lower than the mesosphere temperature in winter."
"In addition, the gaseous particles in the mesosphere are very abundant. On Earth, millions of meteors enter the earth every day and are burned in this middle layer of the atmosphere. After the meteoroids enter the mesosphere, they will collide with the gaseous particles in the mesosphere, which will cause a high concentration of iron or other metal atoms. This collision will quickly produce enough friction to cause combustion, and then the heat will cause these falling objects to be burned out before they reach the surface."
After Chen Mengchuan had a general introduction to Sun Zhongyong, Tenzhi 1 also officially entered the middle level and began to accelerate faster. The speed soon reached 400 kilometers per hour, and it was still accelerating.
In just a few minutes, Artificial Intelligence Ayu in the Tenzhi 1 warehouse reminded, "Old Xu Old Zhang is about to enter the thermal layer. The temperature will increase and the refrigeration system will start in the warehouse. The entire flight will last 700 kilometers until entering the final exosphere."
"Okay, Ayu, thank you for the reminder." Xu Zhenglin said. During this period of time together, Artificial Intelligence Ayu has become another close friend of him and his wife. The couple basically no longer treats Ayu as Artificial Intelligence, but as a real living person, a real human being who seems to be communicating and guiding them through voice on the other end.
"This is what I should do." Ayu replied with a smile.
Soon, Tenzhi 1 turned off the external camera, and at the same time retracted the gravitational external node to assist flight. The entire spacecraft flew towards the boundless abyss of the universe like a huge bullet.
All live video screens are still being introduced and explained. Although the number of viewers has dropped, there are still a large number of people watching the live broadcast and constantly cheering for the two people on Tenzhi 1.
A few minutes later, a screen in the cabin slowly lit up in front of the two people.
"Old Xu, Old Zhang, you are going to be popular this time. More than 2 billion people around the world have seen you two, and more people are constantly cheering you on. Let me show you some translated pictures." Ayu said and put many screenshots of comments on the screen, and the slideshow played quickly.
Xu Zhenglin and Zhang Ying were originally calm. Unexpectedly, when they saw the screenshots of these comments, they could not help but burst into tears. Although they were about to fly out of this planet, they were not alone. There were still so many people on earth supporting them.
"Ayu, can you help me convey some words to the earth?" Xu Zhenglin asked.
"Of course, just tell me, I will transmit the video and voice to the earth."
"Family friends on Earth, I am Xu Zhenglin, and I am now on my way to the moon. We are very lucky to have this opportunity to be a member of the crew to go to the moon. We have seen many of your comments on social media and video media. Thank you for your support."
"Big guys, I am Zhang Ying, thank you..."
The two of them spoke with excitement, and their words were transmitted to people on the earth through Artificial Intelligence Ayu. Under the translation of a group of self-media people, they were quickly transmitted to the whole world...
The flight of Tenzhi 1 continued, and the speed became faster and faster. It soon exceeded 500 kilometers per hour, and the speed continued to increase.
After more than an hour passed, we finally flew to the top of the thermosphere, and then broke through the thermosphere of more than 700 kilometers.
"Old Xu, Old Zhang, congratulations, you have entered the exosphere. Tenzhi 1's flight speed will soon begin to increase significantly. If you feel uncomfortable during this process, please tell me as soon as possible." Ayu said carefully.
"Start accelerating, Ayu." Xu Zhenglin said.
After he finished speaking, Tenzhi 1 quickly began to speed up, and the speed exceeded 1,000 kilometers per hour very quickly!
And as it gets further and further away from the center of the earth, the gravitational pull of the earth begins to become smaller and smaller. The speed of the spacecraft quickly accelerates to 1500KM/hour in a few minutes!
Then it stopped at 1500KM/hour.
"Old Xu, Old Zhang, and Tenzhi 1 have stabilized and can be unbuckled for free movement. We will arrive at the moon in 261 hours and begin flying in a lunar orbit!"
Ayu's words were not only spoken to Xu Zhenglin and Zhang Ying, but also to the command department on Earth.
After she finished speaking, everyone cheered and hugged excitedly!
"There is no doubt that we succeeded!" Chen Mengchuan looked at the picture on the screen, as if he had seen the future!
After unbuckling, Zhang Ying walked to the slowly opened observation window and looked at the huge blue planet. A shiver made her whole body tremble, and she couldn't help but touch the window with tears streaming down her face.
"Hello, Earth..."

The third volume looks at the end of the universe.
